Theme 17-1

Strategy

Lob a Yellow bird and break the wooden plank above the TNT in the middle of the level. Minimize collateral damage as much as possible. With a similar trajectory, bomb into the newly-created gap, triggering the TNT and ideally collapsing the main structure. If you are not so fortunate, fire Big Brother into the top portion of the left tower, causing it to shift rightward and collapsing the structure anyway.
